  1. Hardware and Software Technologies for the Development of Multimedia Instructional Modules Nanda Ganesan, Ph.D. California State University, Los Angeles K. P. Hewagamage, Ph.D. University of Colombo

  2. Overview • Demonstration of modules • Survey of hardware • Survey of software • Summary

  3. I. Demonstration of Modules • Module formats • Module demonstrations

  4. Module Formats • PowerPoint based lecture modules • Chalk-and-talk type of lectures • Simulate the in-class learning environment • Software simulations • Software tutorials • Active learning and learning assessment with quizzes

  5. Module Demonstrations • Module 1: PowerPoint lectures • Module 2: Chalk-and-talk type of lectures • Module 3: Software simulations • Module 4: Software tutorials

  6. II. Hardware Survey • System unit • Input devices

  7. II.I System Unit Consideration • Audio and video synchronization without delay • Time required to manipulate and process recorded audio • Quality of audio • Time required to manipulate both audio and video together • Quality of audio and video produced • Support for high resolution and high color depth recording of multimedia

  8. Comparison of Systems Built

  9. Minimum Guidelines for Processor and Memory • A Pentium 4 processor or above that operates at a clock speed of 3 GHz or higher • A total memory of at least 512 M Bytes of RAM with preference for 1 G Bytes or more of RAM

  10. Minimum Guidelines for Hard Disk • A hard disk with a rotational speed of at least 7200 RPM and a speed rating of at least 100 M Bytes per Second (ATA/100) • A removable USB 2.0 hard disk with a capacity of at least 40 G Bytes

  11. Minimum Guideline for Audio and Video • A video card with a memory of at least 128 M Bytes and a processor that is at least as powerful as ATI’s 9600 Graphical Processing Unit (GPU) • A stand alone audio card similar to SoundBlaster Audigy ZS that would support recording audio at a sampling rate of 44 MHz or more and at a sampling depth of 16-bits or more

  12. II.II Survey of Input Devices • Considered • Display based • Tablet (Pad) based • Paper based • Others • Tablet PC • Digital Pen

  13. Display and Tablet Based Devices • There are certain disadvantages with display and tablet based devices • Display based devices • Inconvenient to simulate electronic whiteboard • Tablet based devices • Sketches cannot be viewed on the tablet while being sketched

  14. Paper Based Products • Seiko InkLink • Pegasus NoteTaker • The above two products had nearly the same functionality • InkLink was chosen due to its wide availability for testing in retail stores and it was found to serve the purpose adequately

  15. III. Survey of Software

  16. III. I Category 1: Adding Multimedia to PowerPoint

  17. Category 1: Continued

  18. Category 1: Selection • For the development of simple modules • PowerPoint recording facility • Microsoft producer • For the development of more advanced modules • Ovation • Impatica

  19. III.II Category 2: Software for General Purpose Screen Recording • Screen recording software with audio capabilities • Modules generated • Low storage requirements • Support for popular recording file formats

  20. Software Grouping • For the purpose of the survey, the software was grouped into two sub-categories, namely the high-end and low-end software categories

  21. Category 2: General Purpose Screen Recording Software

  22. High-End Software • Turn-key CD and e-learning system development • Time consuming task • Macromedia’s software packages generally dominates the market • Expensive to purchase, in general

  23. Low-End Software • Mostly centered on a specific purpose • Recording of screen activities and narration • Designed for rapid application development • Studio versions have many features included

  24. Low-end Software • HyperCam • Microsoft Encoder • Camtasia

  25. HyperCam • Shareware • Limited support • A relatively good and cheap software for recording screen activities • Advanced editing and processing features are limited • http://www.hypercam.com

  26. Microsoft Encoder • Screen recording features are somewhat limited • Designed for generating streamed multimedia modules from other multimedia file formats • Distributed free of charge by Microsoft • Demonstration

  27. Camtasia • A very good software for recording screen activities • Extensive of set of media processing capabilities with respect to screen recording activity • Supports the creation of modules in different media formats

  28. Uses for Camtasia • Recording of screen activities • Adding audio to PowerPoint presentations • Simulation of chalk-and-talk type of lectures • Creations of basic but effective software demonstrations

  29. Category 2: The Choice • From the high-end software category • None • From the low-end software category • Camtasia

  30. III.III Category 3: Software for Authoring Software Tutorials • Extensive features for creating software simulations • In general, the purpose is to record screen images with annotations showing the action taken at each stage • Actions relate to key strokes, mouse clicks etc. • The entire process is done automatically without user intervention

  31. Creating a User in Windows XP

  32. Other Features • Software simulation • Creating quizzes

  33. Leading Software in the Field • Viewlet Builder • By Qaborn • Captivate • By Macromedia

  34. Comparison of Viewlet Builder and Captivate

  35. More on Comparison • Both ViewLet Builder and Captivate have nearly identical features • However, Captivate is relatively easier to learn and use • Moreover, Captivate is better integrated with a host of academic software such as Macromedia Flash

  36. Category 3: Selection • Captivate was chosen for the project • Demonstration of software

  37. III. IV Category 4: Other Software • Microsoft Office • SoundForge sound editing software • Pinacle, Sony VideoBlaster and Adobe Premier Elements • Adobe Photoshop Elements • Roxio Easy CD-Creator • CD-Stomper Label Creator

  38. IV. Summary • Results • Inference • Recommendation • Conclusion

  39. Results • Hardware Survey • System components • Input devices • Software survey • Add multimedia to PowerPoint slides • Screen recording software • Tutorial development software

  40. Inference • Technologies for producing multimedia modules have advanced in power and capabilities • A combination of hardware and software can now be used for the simulation of the in-class learning environment • A new generation of software is available for rapid application development • Hardware and software now available at affordable cost for multimedia content development

  41. Recommendation • Capture the in-class learning experience for the students • Rapid application development tools for the instructor

  42. Conclusion • Properly designed instructional modules can have a positive impact on the learning environment • Learning effectiveness • A host of other benefits • Simulation of in-class learning experience and rapid application development features will encourage instructors to design, develop and use multimedia instructional modules • Use of instructional multimedia modules is likely to become as prevalent as the use of course websites

  43. The End
